Hi everyone,
I've been stuck on following problem for a while: I am trying to model multiphase (gas-liquid) flow through a packed bed for which I am using twoPhaseEulerFoam in OpenFOAM 3.0.1. To my understanding, all I need to do is change following equation ![]() to ![]() where ![]() The alpha-equation solved in fluid.solve() is the one suggested by Weller in Rusche's thesis: ![]() However, this is only valid with equation (1). So, using equation (2) instead, an additional term appears: ![]() where ![]() ![]() ![]() I have tried defining an alphaMax in phaseProperties which should give a bound for the MULES solver, however, this doesn't make a difference. Any ideas on what could be the problem? Thanks Last edited by quir; February 14, 2017 at 10:37. |

Hi
have you solved your problem? I have questions about how you add effect of relative permeability into your solver Roshanak Quote:

hi all
can any body help me please, i want to change my alpha equation for two phase flow in porous media and i need to add effect of relative permeability and capillry pressure thanks in advance |
